Is there a big difference in the length of sleep?

The longer you sleep, the better?! You should have a little different understanding of this. Let me give you a good analysis.

Many studies have shown that sleep time is closely related to the risk of heart disease and other diseases, not as long as you want to sleep, and the normal sleep time is closely related to the age stage. When we were children, we could sleep for about 12 hours every day, which was the best stage of body and brain development. The old people once said, "sleep well, grow fast.".

When we enter the student stage, we sleep 8 to 9 hours a day. At that time, our sleep quality is the best.

When we get down to work, under the pressure of work, family and even society, our sleep quality drops very fast. Sometimes we can only sleep for less than six hours.

When we reach the retirement age, the quality of sleep is even worse. We sleep very shallow and can wake up many times in the middle of the night. At this time, we need to do something to improve our sleep. So if you want to keep healthy, how much sleep time is better?

According to the survey, there is a close relationship between the length of sleep and health. People who sleep less than six hours a day have higher rates of heart disease, stroke and diabetes than people who sleep seven to nine hours a day.

People who sleep less than six hours have a higher incidence than people who sleep more than 10 hours. According to the survey results, the most healthy sleep time is 7-9 hours. Sleeping too long can easily lead to difficulty in sleeping, which in turn affects the quality of sleep. High quality sleep quality is an important guarantee of human health.

When it comes to human health, people don't think that eating a certain kind of food or doing a certain kind of exercise can really get health. It is necessary to balance every element, and interaction can bring health. Sleep is the same. A good improvement of sleep must balance sleep time and sleep quality.

Many people work overtime at ordinary times, often lack of sleep, and then try to sleep late at weekends, hoping to "make up" their sleep at ordinary times. However, such a mode is not really a healthy mode, but it is harmful to the body. Should insist on 7-9 hours of sleep every day, wake up immediately after waking up in the morning, do not lie on the bed lazily, it is better for health and beauty.

In short, sleep time is not about length, but about quality. For example, staying up late and eating irregularly have a great impact on our healthy sleep. It's unscientific to say that it's necessary to make up for sleep. Even if you make up for time, you lose quality.
